NSFW Warning?

I was wondering a couple things related to NSFW (not safe for work) content:

First, I'm sure some of you check out Metalunderground.com at work. Do you consider the content as not safe for work overall?

If not, would you want to be warned specifically about NSFW content ahead of time? Any ideas on how you would like to be warned? Headline with NSFW? Have you seen any interesting techniques used to warn users of NSFW content?

We try to do our best to not feature auto playing or mouseover audio on ads, audio, or video - I think that's important for general use, but especially at work. But I'm curious what other concerns our readers may have.

I'd prefer a discreet warning really - part of me thinks your boss finding 30 pages with NSFW headers in your history would be worse you know? Mostly the issues would be videos I'm guessing ala Rammstein, but in that case a caption above the video would suffice for me. Anyone else's thoughts?

"Rammstein Posts Pornographic Music Video" is probably a bad example. The name just screams 'NSFW', but the topic "Rammstein to Release New Album in Boxset" would need a tag, considering the content. Who would think its covered in dildos? I didn't.
